Yeah, maybe a different way to tackle it. Definitely need to see some data on it.The HKS looks different to the normal drop in baffles. It has that whole cast section which none of the others have had almost making it a sump within a sump. It will be interesting to see the data on it though. HKS are a giant of a company in the tuning world so I hope they have done their homework.
The larger pans work no doubt but is not a cure to the problem. It is just throwing more oil at it.
The gen1 (gt86/brz) had 0.4L higher engine oil capacity. I wonder if by reducing the capacity (for environmental consideration) in the gen2 hasnt helped us here. Hard to tell unless the design of the oiling system is identical between the two though!
